Matters needing attention in planting celery in summer

Celery is a kind of side dish that many people like to eat very much. when cooking, many people like to put some celery into the seasoning. Therefore, the market demand for celery is relatively high, and the planting area is also expanding. So as we gradually enter the summer, there are many places for us to pay attention to when celery is planted in summer. So today, the editor brings you some notes on growing celery in summer. Let's take a look!

1. Sowing and raising seedlings

The temperature in summer is very high, and it is very difficult for celery seeds to germinate in a high temperature environment, so we must pay attention to the germination of celery seeds. In the seed germination, the temperature should be controlled at about 18 degrees, not too high, otherwise germination can not be without great effect. After sowing, we should pay attention to shading and proper watering to ensure that the soil is moist and promote seedling emergence. However, the moisture should not be too much, and drainage should be done well in the rainy season. Then when the seedlings grow two leaves, carry on the inter-seedlings, when the seedling age reaches about two months, the seedlings about 18cm can be called strong seedlings.

2. Planting density

The planting density of celery in summer must be strictly controlled. Only by ensuring the robust growth of each seedling and coordinating the growth relationship between the whole celery and individual seedlings can the yield be effectively increased. The row spacing of planting plants should be controlled at about 7*10cm. In celery for the first time squatting seedlings, control the amount of water, generally watering once a week or so, keep the soil dry and wet. Then, when squatting seedlings for the second time, you should pay attention to controlling the temperature. Improve the permeability of the shed, the temperature is controlled at about 19 degrees during the day and 14 degrees at night.

3. Temperature control

I just said that the high temperature in summer is actually very unfavorable to the growth of celery. Celery has strong cold resistance, but the heat resistance is very poor. When we plant in summer, the daytime temperature should be kept at about 20, and the temperature difference between day and night should be controlled at about 7-8 degrees. If the temperature is too high, it can have a fatal effect on celery. Therefore, when we plant, we must improve the permeability of the shed, properly ventilate and ventilate, and maintain convection. The temperature in the shed can be effectively reduced by ventilation.

4. Adjust the light

Light is also very important for the growth of celery. In the environment of low temperature and long sunshine, celery is easy to bolting because of photoperiod. So we must do a good job in adjusting the light. When planting in summer, if it is planted in a greenhouse, then it is necessary to cover the greenhouse film to avoid direct sunlight, and if it is cultivated in the open field, then the sunshade net must be set up after planting to avoid direct sunlight at the same time. Provide the right amount of scattered light for celery. Then we should pay attention to do a good job in the cleaning of greenhouse film, but also to ensure a certain degree of light transmittance.

The above is a brief introduction to the matters needing attention in growing celery in summer. Growing celery in summer is a lot of things we need to pay attention to. In addition to the above, there are also diseases and insect pests, humidity, fertilizer and so on, which can not be ignored. That's all for today's introduction. This article is for reference only. I hope it can be helpful to all of you.
